Connecting Technology with UV-High Performance andUV-Curable PSA in Electrical/Electronic Industry

UV Curable Solution Acrylic PSA with Optical Clarity

A new Ultra Violet (UV) curable solution acrylic polymer based technology has been under development for manufacturing optically clear pressure sensitive adhesives. Monomers, functional groups, and formulating components can be selected to modify and tailor product properties for specific optically clear end uses. Refractive index, outgassing, heat resistance, and humidity resistance among othe...

High-Performance UV-Curable Urethane Acrylates via Deblocking Chemistry

Research in urethane-acrylate UV-curables has shown that these materials have mechanical properties inferior to those of thermoplastic polyurethanes with very similar composition owing to the high cross-link density in UV-curables; in particular, their ultimate extension is low (less than 100%). Past attempts a t increasing the ultimate extension involved compromising the advantages of the UV-c...

High Performance Double-sided Psa Tape Produced by Uv Irradiation

UV-curable Encapsulants for LED

UV cured epoxy systems represent complementary technology to the established heat cured epoxy systems for coating, adhesion and encapsulation of electronic devices. The UV cured epoxy systems offer significant benefits in terms of fast cure and thus very short production cycle time; low stress and better colour due to room temperature cure; process wise no mix ratio problem or anhydride handlin...

Nanoimprint Lithography with UV-Curable Hyperbranched Polymer Nanocomposites

Nano-scale patterns were produced with UV-curable acrylated hyperbranched polymer nanocomposites using nanoimprint lithography with a glass master in a rapid, low-pressure process. The pattern of the glass master was replicated with composites containing up to 25 vol% SiO2 with a shape fidelity better than 98%. Photo-rheology, interferometry and atomic force microscopy were used to analyze them...
